So, your enterprise has decided to move its data to the cloud. It's difficult to know where to begin until you set your priorities. And priorities are bound to be different for different stakeholders.

A 5 step approach for enterprises in cloud

Ericsson has come up with a five-step approach for enterprises to evaluate their options and make the right decisions:

  • Phase I: Determine your deployment model.
  • Phase 2: Determine your service model.
  • Phase 3: Perform an application requirements analysis.
  • Phase 4: Perform a TCO analysis.
  • Phase 5: Make your decision. This phase includes planning for proof of concept and developing your migration timeline.

Different parts of your business have different goals. Some are concerned with meeting regulations requirements, others with decreasing latency. How can you make everyone happy?

You’ll need to consider whether you’ll be best suited by using a private cloud, a public cloud, or a hybrid cloud. It’s not uncommon to start with one and eventually move to another.

IaaS and bare metal

You’ll need to choose a service model. Will it be the “bare metal” solution in which the cloud provider gives you access to the machinery, and you do everything else? Will it be infrastructure as a service (IaaS), onto which you can install an OS of your choice? Will it be platform as a service (PaaS), in which the underlying OS and middleware are provided, and it’s up to your developers to provide the applications? Or will it be software as a service (SaaS) in which the entire stack is provided, and all you have to do is log in?

If you choose IaaS, then you’ll need to make some decisions about infrastructure components. Which Linux distribution will you use? Ubuntu? Red Hat? openSUSE? And you’ll need to decide what type of network works best. Private or tenant? Provider or storage?

And for a bare metal deployment, you'll need to plan the software-defined networking (SDN) underlay, which depends upon, among other things, the characteristics of your workload and your service chaining requirements. And you’ll have to select the hardware, of course, and find the best hypervisor to work with it.

Niketu Parekh, Sudeep Batra, Rony Haddad, all part of Ericsson’s cloud solutions team, took the stage at OpenStack 2017 in Boston to walk the audience through the process of building a forward-looking cloud strategy. Check out their presentation below.
